MEANS FOR SECUJRZENG WHEELS T0 AXLES.

Specification of ltetters Patent.

Patented July as, into,

Application filed July 24, 1909. Serial No. 509,459.

To all whom it may concern:

Be it known that l, HARRY C. GRANT, a

citizen of the United States, and resident of Bayonne, in the county of'Hudson and State of New Jersey, have invented certain new and useful Improvements in Means for Securing Wheels to Axles, of which the following 1s a specification.

My invention relates to running gear for cars and the object of my invention is to provide a pair of wheels and an axle for toy carsavhich may be easily and cheaply made and held together..

A further object is to prevent the wheel turning relative to the axle.

Referring to the drawings which form a part of th1s specification,-Figure 1, is a front elevational view of the wheels and axle. Fig. 2, is a cross sectional view through the wheels and disclosing the outer surface of'the axle. Fig. 3, is an end view of one oif'the wheels, and Fig. .4, is a view of the op osite end of said wheel.

The ax e A, is preferably made from a piece of .soft steel of circular cross section, and is provided with short oval webs or rejections A, which are formed by prcssmg the metal from the rod by a die to about the form shown in the drawings and ar-,,

ranged one opposite the other on the rod.

The wheel B is made in two parts, both of which are stamped from thin"shcet metal.

.lth portion B is formed in the shape of a disk and is provided with a hole 15" at its center and a recessed or slotted portion 18 located diametrically opposite to each other and of corresponding shape and dimensionsto permit the, webs A of the axle t0 fit therein, the hole B being a close sliding fit with the rod or axle A. The portion of the Wheel I) is formed in the die to pre I sent a tread surface I) and a flange If, the

upper outer edge of which is pressed over the periphery of the disk portion at (J to form a joint shown. The portion B is further provided with a short tubular portion 6 which is'drawn to form from the metal as shown, and a recess or annular groove 6 is also formed in the pressing operation. The metal is sufliciently thin to conform to the axle A when the end of the same is forced into the tubular portion i2 and expands sutliciently under the pressure to form a tight frictional joint between the axle and tubular portion, and when the axle is in position shown, the webs A are located in the slots 13 and effectually pro vent the axle from turning relative to the wheel, even though the frictional joint at B were to become loose by reason of the tubular portion splitting or from any other cause. The ends of the axle project through the wheels a sullicient distance to serve as bearings and are adapted to rest in the journals of the truck frame in the usual manner.

lBylt-he present construction I have overcome a number of difficulties heretofore encounteren'l in making this part of the car gear and have provided a strong and durable construction of exceptional lightness and easy to assemble.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, isi 1. In combination, a wheel comprising two parts one of which is provided with a central bearing surface and the other of which has a slot adapted to receive a web; and an axle having a web located in said slot and one 'end of which engages said central bearing surface.

2. ln combination, a wheel comprising two portions made from sheet metal andv held together at their peripheral edges, one of said portions having a central tubular bearing surface; and an axle having a web t'ormcd integral therewith and engaging one of said portions to prevent relative rotation, and scoured'to said wheel by frictional engagement between said axle and said tubular bearing surface.

Signed at city of New York in the county of New York and State of New York this 20th day of July A. l). 1909.
